Two weeks ago I moved this website from a shared account to a VirtualPrivateServer wit 8GB Ram and 2Vcores.
In addition I moved the critical parts like js, css and pictures to ContentDeliveryNetwork.
This eliminates the need of questionable and sometimes inkompatible tricks like Browser caching, minifying aso..
Advantage: Usualy the pages are now delivered in less than 2sec to all kinds of browsers
Downside: Costs 378.–€/Year
Anyway, I don’t like to stop half the way – so enjoy it.
Best regards, Christian
